i am seeing this after it was validated (for what, who knows? i don't see anything that would trigger a dq request...). it does look over-processed. there is a fair amount of banding in the skies, and the wires are showing a lot of haloing. i imagine you were trying to correct for a soft focus, which could have been prevented with a tripod.
On my screen it is slightly oversharpened (halos around the hard edges like the barb wire) and there is a strange circular gradation in the sky.
But apart from that;
Interesting photo to look at, composition is good, sky is interesting, especially that strange blur that makes the clouds so fluffy. I like the dark tone of your sky vs the brightness of the stuff in front. The subject does not really make a strong impact on me.
